对这类水晶晶簇观赏石的欣赏与评价，主要是强调晶体的完整、品种的名贵（如紫水晶、烟晶、发晶等）、造型奇特、含有名贵晶体（如辰砂、辉锑矿等）伴生等。晶簇产于矿床晶洞中，长相完美的并不多见，要完整无损地采集下来，又比较困难，故而采集起来代价较大，精品晶簇价值也就昂贵了。
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
A crystal structure concentrates on how the atoms are arranged In the crystal. On the other hand, crystallographers are interested in the overall form and sizing from the crystal along with its external traits. To accomplish this, they have to find out about the crystal system.
If you'd like to see how crystals are fashioned, you are able to perform a little project inside your quite personal kitchen area and find out the development on the crystals happen with your personal eyes . This can be finished by Placing a little level of desk salt into some regular faucet h2o, wait around 24 several hours, and you will see pleasant cubed formations. This transpires since the water is evaporating, which triggers the atoms that make up the salt (the mineral) along with the water to come back nearer collectively.

Crystallography is the analyze of crystals, and it promotions with every thing from excellent geometric designs to seemingly random conglomerations of particles and minerals.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
